^^^^^Agree. "Lack of rain" maps is not a good indicator of "crop condition" maps unless your indicating lawns or poorer ground pastures (shallow rooted grass). There is such a difference in water holding capacity of soils. You can have the same rainfall amount in 2 different areas and two totally different looking crops. I have personally seen time and again areas where producers are complaining of "drought" and crops still look good. I totally agree the areas in "red" in Iowa are way behind in rainfall. But you lay a water holding capacity map over the drought monitor map,  and a big portion of that area has good subsoils with it fully charged last fall.
Are the reserves gone now? Yes. Was top end loss? Yes. Rain has been very spotty this year and have seen pockets that are fired, probably beyond repair, even with the good rains areas of West Central and South West Iowa have enjoyed the past 10-14 days. Most of the "Red" areas in Iowa, according to the Drought monitor (I know soils vary in pockets), can hold on probably a good 2 maybe 3 weeks longer than areas in South Central, North East and East Central Iowa. If the drought monitor map was red in the areas previous mentioned, those crops would already be "toast" vs "hanging on".
Timing is everything also. Soybeans are made in August and corn can turn from decent ears to partial ears of popcorn.  Hopefully the "red" areas can hang on long enough where August rains can save what they have in corn and give a good charge to their beans. Eastern half of Iowa is now DRY/VERY DRY. White beans in August generally doesn't bode well for yields nor does flat corn that pushes pollination back a good week or two. Hopefully predicted "scattered" rains Saturday produces moisture for everyone!!!
Personally think FC Stone is too high on corn for Iowa. Too many statewide strikes against it. Cold spell early for the whole state, dry conditions from mid to now late season in a good portion of the state, and areas that had decent moisture mid season experienced acres and acres of flat corn. Think they are a little high on soybeans also. But who knows, August rainfall(or lack of), is huge on beans. Jury still out on those.
